vision.image-request@1: one image for OpenVibe.Vision's one-shot tools, as a data URL or a public URL. The multipart form field \`image\` carries the same bytes. Private tools (find, index, watch, moments) accept only uploaded bytes or a data URL, never an unverified source URL.

## Fields

| --- | --- | --- | --- | --- |
| `image` | string |  | The image as a data URL (base64). | - `pattern ^data:image/` |
| `image_url` | string |  | A public image URL, fetched through Vision's private-address guard. | - `pattern ^https?://`<br>- `format uri` |
